Flags for the json_valid function

These flags define what is meant by “well-formed” JSON when validating.

The following bits are currently defined:

• 0x01 → The input is text that strictly complies with canonical RFC-8259 JSON, without any extensions.
• 0x02 → The input is text that is JSON with JSON5 extensions.
• 0x04 → The input is a BLOB that superficially appears to be JSONB.
• 0x08 → The input is a BLOB that strictly conforms to the internal JSONB format.

By combining bits, the following useful values can be derived:

• Rfc8259Json (1) → X is RFC-8259 JSON text
• Json5 (2) → X is JSON5 text
• JsonbLike (4) → X is probably JSONB
• Rfc8259JsonOrJsonb (5) → X is RFC-8259 JSON text or JSONB
• Json5OrJsonb (6) → X is JSON5 text or JSONB (recommended for most use cases)
• JsonbStrict (8) → X is strictly conforming JSONB
• Rfc8259JsonOrJsonbStrict (9) → X is RFC-8259 or strictly conforming JSONB
• Json5OrJsonbStrict (10) → X is JSON5 or strictly conforming JSONB

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rfc8259Json = 1

X is RFC-8259 JSON text (flag = 1)

Json5 = 2

X is JSON5 text (flag = 2)

JsonbLike = 4

X is probably JSONB (flag = 4)

Rfc8259JsonOrJsonb = 5

X is RFC-8259 JSON text or JSONB (flag = 5)

Json5OrJsonb = 6

X is JSON5 text or JSONB (flag = 6, recommended for most use cases)

JsonbStrict = 8

X is strictly conforming JSONB (flag = 8)

Rfc8259JsonOrJsonbStrict = 9

X is RFC-8259 or strictly conforming JSONB (flag = 9)

Json5OrJsonbStrict = 10

X is JSON5 or strictly conforming JSONB (flag = 10)
